It is not the visibility of the driver that makes a tint legal or not. It is the visibilty of the officer that makes it legal or not. The principal of light refraction is at work here. The side of any glass with the most light acts like a mirror and it is very difficult to see in. You can see out but they can't see in. Basically, anything not "factory tint" is ILLEGAL in California!
And it is not a secondary ticket. They can pull you over just for that reason!
